6. Numeric and Mathematical Modules
</h1>

<p>
The modules described in this chapter provide
numeric and math-related functions and data types.
The <tt class="module">math</tt> and <tt class="module">cmath</tt> contain 
various mathematical functions for floating-point and complex numbers.
For users more interested in decimal accuracy than in speed, the 
<tt class="module">decimal</tt> module supports exact representations of  decimal numbers.

<p>
The following modules are documented in this chapter:
